NEW HAVEN >> The Coast Guard is telling boaters a rotating bridge along the Metro-North Railroad will have limited openings to river traffic so train service won’t be affected by planned repairs.

The Coast Guard says in a notice that the Connecticut Department of Transportation has contracted engineers to make emergency repairs as soon as possible. The repairs are expected to take several weeks depending on the extent of damage.

The Walk Bridge, over the Norwalk River in southwestern Connecticut, was stuck in the open position on Friday and last month, snarling commutes for thousands of riders. The bridge has been kept in the closed position to ensure train service is not affected. Under normal conditions it is opened to allow boats to pass beneath.

A Coast Guard spokesman says the bridge will be lifted on a case-by-case basis to allow boats to pass beneath.

Metro-North is the nation’s second-largest commuter line after the Long Island Rail Road.

Amtrak service was also affected when the bridge was stuck open.

U.S. Sen. Richard Blumenthal, D-Conn., earlier this week requested that the Coast Guard restrict when the bridge swings open for boats.

On Monday, Gov. Dannel P. Malloy held a “crisis summit” with state, Metro-North and MTA officials in New York to discuss the bridge issue.

The bridge is owned by Connecticut. In April , the state applied for $349 million in federal transportation funding to help replace the bridge, which was built in 1896. The state won’t know until fall if that is approved.
